invention, such as will enable others .skilledr in the art to which it appertains to make and use the same.

This invention relates to vapor forming devices for internal combustion engines, and one of the principal objects of the invention is to provide means :for converting coal oil or other oils heavier than gasolene into gas and mixing the same with air to be used for charging internal combustion engines.

Another object of the invention is t0 provide means for treating coal oil or other oils heavier than gasolene through a pipe :from a tank into the exhaust pipe of the engine to heat the .same and to convert the oil into gas, a gasolene starting device being employed to give the additional. impetus to the engine and to be then cut oli after the oil has been suiliciently heated in the exhaust pipe to be converted into gas.

rlhese and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which,

Figure 1 is a diagrammatic vieu7 showing the exhaust pipe in section and illustrating the manner of treating the coal oil to be converted into a gas, Fig. 2 is a vertical sectional view of the gas pipe and carbureter, Fig. 3 is a detail sectional view of the coal oil lloat, Fig. l is a detail plan 'View of the upper end of the air inlet oit' the carbureter, and Fig. 5 is a detail view showing the manner of connecting the gasolene stockingpipe to the dashboard of the vehicle.

Referring to the drawings, which show the invention ,connected to parts of a four cylinder internal combustion engine adapted to be used on motor vehicles, the numeral l designates a gasolene tank of small size. A gasolene pipe 2 extends from the tank 1, and is connected to the dashboard 3 by extending from the underside through the same and back again, at 'which point a needle valve i is provided. From this point the gasolene pipe 2 extends to the up-k per part of the carbureter 5; This arrange- Specification of Letters Patent.

nient is used for the purpose of starting the engine preparatory to the use of coal oil as a fuel.

The coal oil tank 6 is provided With a discharge pipe 7 which leads to a float 8 comprising a casing having a float regulator 9. therein. From the float the discharge plpe 10 leads into the exhaust pipe 11 at the point 12 adjacent the muffler. The pipe 10 contains the coal oil upl to substantially the point 13 and this level of coal oil `is regu lated by the float'. When the oil in the pipe 10 is sufliciently heated to convert the gasolene into gas it is led from the point 13 up and out the exhaust pipe 11 at the point 15 where the pipe 10 goes up into another pipe or gooseneck 14 which ts over it in such a manner as to let a little of the gas escape in case of excess pressure. This pipe or gooseneck 14n is Wrapped With asbestos 16 so that it Will hold the heat and conduct the gas to .the carbureter 5.

The carbureter 5 is provided with a cup or bowl 18 to catch any ofthe coal oil which has not been converted into gas and this bowl is provided with a lip cock 19. The air enters the mixer through the opening 20 which surrounds a spider 21 seated in the end of the air inlet, and a valve 22 provided with a stem 23 extending through the spider is seated in a flaring valve seat 24 and adjusted relatively to the seat to regulate the supply of air by means of the threaded valve stem 25 extending through the casing and provided with a hand wheel 26. The nlixer is provided With a discharge branch 27, in which is seated the throttle valve 28 and said branch at its upper end is provided with branches 29 which lead to the engine cylinder. Other heavier oils may be used in the same Way as coal oil, but they are not quite as reliable as coil oil. The exhaust enters the o'ur points 30.

The operation of the invention may be briefly described as follows: In starting' the engine, the valve 4 is opened and a supply of gasolcne is led from the tank 1 to the carburetor 5 for initially starting the engine. After a few revolutions or impulses of the engine, the exhaust pipe 11 is heated Sulliciently to convert the coal oil inthe pipe 10 --Wi'tl air and led to the engine.

From the foregoing it will be obvious that an apparatus made in accordance with this invention Will utilize coal-oilasa fuel, for yinternal combustion engines, thus cheapening the cost of running the engine, and at the same time providing a reliable and ei cient fuel which is more reliable and less dangerous than the ordinary gasolene.

Various changes may be made in the details of construction Without departing from the spirit and scope of the invention as de- .ned in the claims.

What is claimed is 1. A vaporizing device for internal com bustion engines comprising a carbureter and a tank, an air mixer formed on said carloureter, an air supplyr valve mounted in said air mixer, means for regulating said valve, a cup formed on the -lower extremity of the carbureter and provided with a drain cock thereon, a gasolene pipe leading from the tank and connected to the upper end of said carbureter, a goose neck pipe connected to'the carbureter adjacent the cup and teriminating adjacent the exhaust pipe of an "iengine, an oil pipe adapted to lead-through the exhaust pipe of an engine and connected with said goose neck pipe, and means for regulating the How of oil Within said oil Plpe 2. A vaporizing device for internal combustion engines comprising a carbureter, an air mixer formed on said carbureter, a gasolene pipe connected to said carbureter, a goose neck pipe connected to thc carbureter and terminating adjacent the'exhaust pipe of an engine, an oil pipe leading from an oil tank adapted to enter the exhaust pipe of an engine adjacent the outlet end and exit adjacent lthe inlet port and connected to said goose neck pipe, a float regulator connected to said cil pipe to control the level of oil within the oil pipe, and 'means for allowing the excess pressure of gas within the oil pipe to escape.

in testimony whereof I afiix my signature in presence of two Witnesses.
